Former House Speaker Nancy Pelosi (D-Calif.) suggested Monday that Russian President Vladimir Putin has some sort of financial influence over former President Trump.

In an interview with MSNBC’s “Inside with Jen Psaki,” Pelosi said Putin is the “richest person in the world” and has “stiff competition” to being named the most evil person in the world.

Pelosi asked “what does he have on Donald Trump that he’d have to constantly be catering to Putin?”

Her comments came just after Trump doubled down on his criticism of NATO and said he would encourage Russia to attack U.S. allies who fail to reach the alliance’s defense spending goals. Trump has also declined to criticize Putin for the death of opposition leader Alexei Navalny in a Russian prison last week.
